Refinement of the selection of categories for importing goods from the supplier Brain

Not really a good idea due to the specific architecture of Brain...
For Brein, for example, the category Batteries can be in 3 different categories and it’s not a fact that the category you choose will be with them or that the same item will not be loaded 3 times for 1 import
There you can catch something like this: you load laptops, they have headphones in them, they belong to the accessories subcategory on their website, but they will fall into the box without a category. a category comes from Brein - headphones from the Audio section, which is not loaded according to the settings
IDs of the categories of the same name of the categories of the brain are all different.
How can I do that, but I can not give guarantees that it will work adequately

You are probably talking about looping through all the products and seeing if the category fits, which is not exactly what I'm suggesting.
If you write the category id http://api.brain.com.ua/products/1191/ in the request, then it returns only the products that are there
+ you can add id in brackets to the category name to understand what I choose
And if several categories are selected for import, then for each category form a separate request http://api.brain.com.ua/products/category_id/

And I will put down one category for everyone (I already evaluated it) or fill it without a category

Just now, even if you select a category, the action works for half a day and the relevance of the downloaded data is questioned + flooded, for example, 25k for the same laptops, although there are 1-2k laptops themselves and they can be downloaded much faster

I can refactor so that the categories from Brain are all + checks for imports of only the main categories - this will take about 3 hours.
Get what you choose - then it will import (if it finds a category - into it, otherwise - without a category).

I didn't quite understand what you're suggesting, I want only certain categories of products to be loaded, I suspect it's not exactly what you wrote.
It turns out that it will still shovel all the products, and it will check the category in them and load its products?

No. Now it loads the main categories - and there will be only those that you choose from the entire list (instead of just the main list).
That is, if you select some main and another child, it will import all products on the main and all on the child.

That is, it will be possible to select any category, but there will also be a checkmark that you need to upload only by the main category, as before? If yes, then it is suitable, will this reduce the time of the action?

and as for the category ID, you need to see

okay thanks.
as we decide, I will write
